This invention relates to improvements in concrete curbing.

'Ille general object of the invention is to provide an improved concrete curbing or similar structure pre-cast in sections before it is laid in position.

Another object of the invention is to provide a sectional concrete curbing including novel means for connecting the sections thereof together.

A further object of the invention is to provide a sectional concrete curbing including means whereby the sections may be connected either temporarily or permanently.

Other objects and the advantages of this invention will be apparent from the following description taken in connection with the accompanying drawings wherein:

Fig. 12 is a vertical longitudinal section through a plurality of concrete curbing sections showing further modified form of connecting means, and

Fig. 13 is an end view of one of the curbing sections shown in Fig. 12.

Referring to the dr wings by reference characters I have indicated a section of my improved concrete curbing generally at If?. As shown each curbing section i6 comprises a body portion l2 which is substantially rectangular in shape and which includes a top wall i3, a bottom wall l, side walls i and l5 and end walls il. The top and bottom walls yare shown as parallel with the end Walls 'l and the side Wall l 5 at approximately right angles thereto while the side wall i6 is inclined downwardly and outwardly.

Adjacent each end the body l2 has a recess i8 therein which opens through the adjacent end and includes a bottom surface i9, a topy surface 2D, an end surface 2i, and side surfaces 22 and 23. The bottom recess surface i9 is parallel with the bottom wall M- of the body and the side recess wall 22 is parallel with the side body wall l5 while the side recess wall 23 is inclined parallel 1U with the inclined body wall I6.

The top recess surface is inclined downwardly and inwardly and the end recess surface 2| is inclined upwardly and forwardlyto meet the top surface 2li. Adjacent each end the body 15 l2 has a transverse aperture 2t therein one end of which opens through the inclined side wall iii and the opposite end into the adjacent recess i8. Opposite each of the apertures 2li and in line therewith the body has a recess 25 therein zo which opens into the adjacent end recess I8. (See Figs. 3, 5, and 6.) Intermediate the end recesses lli the body l2 has a recess 26 therein which opens through the bottom surface lll. Around the bottom edges of the recess 25 the z5 body l2 has an undercut recess 2l therein. Intermediate the ends of the recess 25 the body in cludes a plurality of spaced integral rib members 28 which at their lower ends terminate flush with the bottom edge of the recess 25. 30

Positioned in the undercut recess 2l I provide a concrete closure slab 29 which is secured to the body l2 by cementing it thereto as indicated at 3D. When the closure slab 2S is placed in position a quantity of cement may be placed on the upper face thereof adjacent the locality of the ribs 23 to cement the lower ends of the ribs to the closure slab as indicated at 3l in Fig. 2. Although I have shown and described the body l2 as being hollow it will be understood that it 40 may be made solid.

For connecting two sections lil of my improved curbing I provide a key member which is indicated generally at 32 and shown in detail in Fig. 7. As shown the key member 32 includes a body por- 45 tion 33 which is made of concrete and includes a bottom surface 3G, a top surface 35, end surfaces 35 and side surfaces 3l and 33. The bottom surface 3i and the side surface 3'! are approximately at right angles to each other while the side surface 38 is inclined upwardly and inwardly and the end surfaces 36 are each inclined upwardly and inwardly. I

From a point 39 intermediate `the ends 36 the 55 top surface is inclined downwardly towards each end 36 as indicated at 48.

In the sides 31 and 38 of the body 33 adjacent each top corner thereof the body 33 has a recess 4| therein which opens through the top surface and the adjacent end surface. In the sides 31 and 38 the body further includes adjacent each bottom corner thereof a recess 42 which opens through the bottom surface and the adjacent end surface.

Within the confines of each of the top recesses 4I the body has a transverse aperture 43 therein. In each side of the body 33 adjacent each end thereof the body has a secured groove 44 therein each of which at one end opens into a top recess 4I and at the opposite end opens into a bottom recess 42.

From the foregoing it will be seen that the general shape of the key member 32 at each side of the point 39 corresponds to the shape of the end recess I8 of a curbing section IU.

When connecting two of the curbing sections I a key member 32 is positioned in one of the end recesses I8 of the curb and when so positioned the point 39 of the key is flush with the adjacent end surface of the curb thereby leaving half of the key member projecting beyond the adjacent end of the curb. Thereafter another curb section is laid with one end I1 facing the key member 32 and moved towards the key member until the projecting portion of the key member is positioned in the adjacent end recess I8 of the record block as clearly shown in Fig. 2 thus forming a connecting joint 45.

When the curbing sections I0 are laid for temporary use a metal pin 46 is positioned in the aperture 24 of the curbing and extends through the key aperture 43 into the recess 25 of the curb as clearly shown in Fig. 5.

When two sections of curbing are thus connected the key member 32 prevents relative transverse and vertical movement of the curb sections and the pins 46 prevent relativeV lateral movement of the curb sections.

When the curbing is laid for permanent installation the pins 46 are omitted and cement forced by a cement gun, into the lcurb apertures 24. This cement is forced through each of the apertures 24, through the key apertures 43 and into -the curb recess 25 thus forming a cement plug member 41. At the same time cement fills the key recesses 4| and passes down the key grooves 44 into the key recesses 42. Thus it will be seen that when the cement hardens the key member is firmly cemented to each of the curb sections with which it is associated and that the cement plug 41 prevents relative lateral movement of the curb sections. preferably imbedded in the ground as shown in Fig. 5.

`In Figs. 1 and 8 I have shown my improved curbingassembled for use and have shown various other forms as -well as the straight sections I8, into which my improved curbing may be made. At 48 I have shown a corner section of curbing and at 49 Irhave shown a section of curb-y ing in the form of a cross while at50 I have shown asection of curbing in the form of a T. At I have shown curbing formed semi-circular as at 52 andit is formed into quadrants.

The sections V4t, 4S, 58, 5| and 52 are all formed with recesses I8 in which key members 32 may be positioned to form a connecting joint 45. At 53 I Vhave shown a straight section of curbing similar In usethe curbing sections are to the curbing Ill which intermediate its length has a recess I8a therein which opens through one side of the curbing to receive a key member 32 to form a joint 45. From the foregoing it will be seen that my improved sectional curbing may be made in any form desired.

In Figs. 9, l0 and l1 I have indicated a modied form of curbing section generally at 55. As shown each curbing section 55 comprises a body portion 5f; which is substantially rectangular in shape and which includes a top surface 51, a bottom surface 58, side surfaces59 and 60, and end surfaces 6I. The top and bottom surfaces are shown as parallel with the end surfaces at right angles thereto while the side surface. 60 is inclined downwardly and outwardly. Adjacent each end the body 56 has a recess 62 therein which opens `through the adjacent end and through the side surface 58 thereof and includes a side surface 63, an end surface 84, a top surn face 85 and a bottom surface yIl'. The end surface 64 of the recess is shown as substantially parallel with the end surface of the body while the top recess surface isinclined downwardly and outwardly and the bottom surface is inclined upwardiy and outwardly. Adjacent each end the body 55 has a vertical aperture 61 therein one end of which opens through the top surface 51 thereof and the opposite end opens into the adjacent end recess 82. Opposite each of the apertures 61 and in line therewith the body has a recess G8 therein which opens into the adjacent end recess (i2. Intermediate the end recesses 62 the body 55 hasa recess" 89 therein which opens through the bottom surface 58. Around the bottom edges of the recess 68 `the body 56 has an undercut recess therein. Intermediate the ends of the recess 69 the body includes a plurality of spaced rib members 1I which at their low'er ends terminate lflush with the bottom edge of the recess 89.

Positioned in the undercut recess 18 yI provide a concrete closure slab 12 which is secured to the body 55 by cementing it thereto as at 13. When Vthe closure slab 12 is placed in position a quantity of cement may be placed on the upper face thereof adjacent the locality of the ribs 1I to cement the lower ends of the ribs to the closure slab as indicated at 14 in Fig. 9.

For connecting two of the curb sections 55QI provide a key member 15 which includes a body portion 1B made of concrete and having a bottom surface 18, a top surface 19, end surfaces 88 and side surfaces 8| and 82. The end surfaces 3i) are at approximately right angles to the side surface 8| while the side surface 82 is inclined downward and outward. From a point 83 Vintermediate the length of the body the topsurface 19 is inclined upwardly and outwardly and from a point 84 intermediate the length of the ybody the bottom surface 18 is inclined downwardly and outwardly.

In the side 8| of the key body 18` adjacent each top corner thereof the body 15 has a recess 85 therein which opens through` the top surface 19 and the adjacent end surface. The side 8|Yfurther includes adjacent each bottom corner thereof a recess 86 which opens through the bottom surface and the adjacent end surface. Intermediate the length of each top recess 85 the top surface 19 has a transverse recessed groove 81 therein one end of each of which opens into its associated recess 85 and the opposite end of which terminates at a position space-d from the side surface 82. (See Figs. l0 and ll.) v Intermediate the length of each bottom recess 86 the bottom surface 18 has a transverse recessed groove 88 therein one end of each of which opens into its associated recess 86 and the opposite end terminates at a position spaced from the side surface 82.

Intermediate the length of the grooves 8l and 88 the key body 'i5 has an aperture 89 therethrough one end of each of which opens through the top surface 'i9 and the opposite end through the bottom surface 18.

From the foregoing it will be seen that the general shape of the key member 'i5 at each side of the points 83 and 84 corresponds to the shape of the end recesses 52 of a curbing section 55.

When connecting two of the curbing sections 55 they are positioned with adjacent ends abutting and with adjacent recesses 82 in alignment. A key member 15 is inserted into the end recesses 62 of the curb sections from the sides 82 thereof and when so positioned the points 88 and84 of the key are. flush with the adjacent end surfaces 6| of the curb thereby leaving half of the key projecting in one of the curb sections and the other half in the other curb section.

From the foregoing it will be seen that the key member prevents relative vertical and lateral movement of two connected curb sections.

When the curbing sections are lai-d for temporary use metal pins 90 are positioned in the apertures 6l of the curbing sections and extend through the key apertures 89 into curb recesses 68 as clearly shown in Figs. 9 and 10. The pins 98 prevent relative transverse movement between adjoining curbing sections.

When the curbing is laid for permanent installation the pins 88 are omitted and cement forced by a cement gun, into the curb apertures 61. This cement is forced through each of the curb apertures 51, through the key apertures 88 and into the curb recess 68 thus forming a cement plug 9|. At the. same time cement lls the key recesses 85 and 85 thus when the cement hardens the key member is firmly secured to the curb sections with which it is associated.

In Figs. 12 and 13 I have indicated a further modified form of curbing section generally at S5. As shown each curbing section 85 comprises a body portion 95 which is substantially rectangular in shape and includes a top surface 97, a bottom surface 98, side surfaces 99 and it, and end surfaces 02 and 02. The top and bottom surfaces are shown as parallel with the end surfaces at right angles thereto while the side surface is inclined downward and outwardly. Intermediate the ends 6! of the curbing section 95, the body 95 has a recess 183 therein which opens through the bottom surface 98 thereof. Around the bottom edges of the recess H33 the body has an undercut recess Hill therein. Intermediate the ends of the recess H33 the body includes a plurality of spaced integral rib me.i bers |011 which at their lower ends terminate ush with the bottom edge of the recess |83.

Positioned in the undercut recess it I provide a concrete closure slab 185 which is secured to the body Q6 by cementing it thereto as indicated at |05. When the closure slab is placed in position a quantity of cement may be placed on the upper surface thereof adjacent the location of the ribs H34 to cement the lower ends of the ribs to the slab H35 as indicated at 591 in Fig. l2. At the end 182 the body 95 has a plurality of dowel receiving recesses |08 therein which openthrough thewend Vsurface HB2.,y and are` shown as three in,

number, one being positioned adjacent the top of the body and two adjacent the bottom thereof. At the end 3182 the body has a plurality of dowel pin members W99 embedded therein with portions of the dowels extending beyond the end surface E82. The dowel pins 89 yare shown as three in number and are positioned to correspond to the positions of the previously described dowel receiving recesses 98. (See Fig. 13.)

Embedded in the curbing body 95 adjacent each of its ends I provide a pair of superimposed transverse pin members i it each of which at each side of the body extends beyond the adjacent surface thereof land incudes an enlarged head portion i i2 spaced from the adjacent side of the curb body. Mounted on each pin of a pair of the pins Il@ at one end of the curb body I provide a securing member i i3 which is shown as a length of malleable iron wire wound around the pin I l 5 and bent around itself as at Ml. Each of the securing members extends outward beyond the adjacent curb end a predetermined distance.

With the curb sections Q5 a joint member H5 is preferably used. The joint member i I5 may be made of presswood, bako wood or other suitable material 'and has dowel apertures HS therein which correspond in positioning to the positio-ning of the dowels its.

When the curbing sections 95 are laid they are placed with the end D82 of one curb section facing the end 82 of the next adjacent curb section and a joint member l l5 is positioned on the dowels H89 and then 'the dowels are positioned in the dowel recesses of the adjacent curb section and the two curbing sections moved together until the adjacent end faces thereof firmly engage the joint member H5 as clearly shown at the A location in Fig. l2. When the curbing sections are thus brought together the operator ascertains that the fastening members llt of the one section overlietheir associated pin members il@ of the adjacent section as shown at the A location. Thereafter the operator bends the free ends of the securing members i i3 down and around their associated pin members i M3 las shown at the B location thereby securely connecting the two adjacent curb sections together.

The securing members i i3 prevent relative lateral movement between two adjoining curb sections and the dowel pins 33 prevent relative vertical and transverse movement between the curb sections.

From the foregoing description it will be apparent that I have provided a novel sectional concrete curbing which is simple in construction and highly efficient in use.
